It seems there is already ample space for a D4M under the Trottiscliffe Road and Roughetts Road bridges, in theory they would only have to demolish two more bridges and build three new ones, and then one could have a D4M from J3 to J4. That'll never happen, of course.

No need to demolish anything - "Smart Motorways" providing D4 in a D3M footprint are the future apparently and its likely that this will be required at some stage given traffic levels on this section of the M20.

They may have to demolish Bull Road Bridge, doesn't look like there's enough space even for a D4 there.

I guess they would try and have it work with a dodgy lane gain/drop, but it would be tight.

What might be an issue is bridges being too low over the hard shoulder.

Five months of works on the way to replace it.

Does it really take 5 months when the bulk of the work is already there? The foundations are being reused for example.

It's like we just enjoy having cones out for as long as possible sometimes.

The last new footbridge I built took three months and were offline new build. I've got one footbridge to build next year which will take five months as part of an on-line upgrade.

There's probably quite a bit if work making good the existing structure to receive the new sections. Because of its location I imagine the bulk of work will be done at night as you only have the hard shoulder as access in the day - tricky to get plant and equipment in to do stuff.

What I don't understand and perhaps someone here can explain is why these works can't be done concurrently with the Smart Motorway works instead of immediately preceding? In my eyes this is done to make it easier for the engineers and never mind the road users - but I would be only to happy to be corrected.

Thanks,
